What we are sharing today may be that a lot of people feel that it is not meaningful, but it is not meaningless, but it is more cumbersome to use, because after the SELinux security policy is enabled, each application's access domain and file security tags need to be strictly matched to perform access operations, So if a bit of improper setting, it will cause the application error, but anything is double-sided, it is more cumbersome to set up at the same time, but also to the corresponding appli

SElinux is the United States National Security Agency (NSA) implementation of mandatory access control, is the most outstanding new security subsystem in the history of Linux. The NSA is an access control system developed with the help of the Linux community, where the process can only access files that are needed in its tasks, under the constraints of the access control system. SELinux is installed on Fedo

Guide If you have disabled or ignored SELinux in your previous Linux career, this article is written specifically for you: This is an introduction to the SELinux system that exists on your Linux desktop or server, and it can restrict permissions, Even eliminate the vulnerability of the program or daemon process and the likelihood of damage. Back in the kernel 2.6 era, a new security system was introduced to provide a mechanism for access control security policies. This system is

-bit grouping with 128-bit output. MD5 is more complex than MD4, and it is a bit slower to calculate, but more secure. MD5 is not safe enough. SHA1 (Secure Hash algorithm) is designed by the NIST NSA, and its output is a 160-bit length Hash value, so it's better to be poor. The SHA-1 design is based on the same principle as the MD4 and imitates the algorithm. To improve security, the NIST NSA also designed

was connected to Linux, and it all started in the 1994 Goddard Space Center's first named Beowulf supercomputer.According to our standards, Beowulf is not the most advantageous. But at that time, as the first homemade supercomputer, its 16 Intel 486DX processors and the 10Mbps Ethernet bus were a great feat. Beowulf was designed by the NASA contractor Don Becker and Thomas Sterling, the first "maker" supercomputer. Its "compute part" 486DX PC costs j

Install a remote video conferencing system you can take three ways; 1. Budget is relatively more: than can take all the hardware way to do! Structure is the main venue required equipment: An MCU, a terminal, conference-specific camera, audio Mike, display equipment! The branch place uses the equipment is: The terminal, the Conference special-purpose camera, the sound microphone, displays the equipment. This method to achieve the first simple operation is simple! Maintenance is the easiest way f

you for it? The current domestic environment, although everyone may be used "free", but for enterprises, this is to take legal risks.In summary, the enterprise on the MS thing really not cold, ms things really not suitable for large enterprises, in addition to desktop operating system. So with Ms Things, are small businesses, the dependence on MS is not high, so the low wages are very normal. However, this is only a general objective phenomenon, as long as you technology, business ability, no m

embedded projects, matrix organizations are often used. An engineer has both a project manager and a department manager. If the department manager and the project manager cooperate sincerely, can effectively enhance the organization efficiency. Of course, the premise is that the company must have a good PM. The first company I worked for also set up a PMO department where each PM was responsible for one project. But unfortunately, most of the PM lack of experience, as an embedded project PM no

other words, how to provide employees with work and encroach on the functions of the company, and limit the contractor to complete the required tasks? The solution is to divide the tasks into several tasks and then implement the necessary multiple interfaces. PHPS supports this feature. Consider the following example: the difference between an abstract class and an interfacean interface is a special abstract class, or it can be seen as

Before you try a solution, talk about it, often find many traps and prevent detours. I can't remember how many times the first five minutes of discussion in preparation for a task was "Wow, this is wrong." ” In case you win the lottery or retire, you're just training a replacement.

Grid Grid is hailed as the third wave of information technology following the Internet and the Web. In fact, the reason why grid technology can cause

1. Concept: CMM is Capability Maturity Model for software abbreviation, Chinese called "Software Capability Maturity Model", is the organization software process capability description. The core of CMM is to regard software development as a process, and to monitor and research the software development and maintenance in accordance with this principle, so as to make it more scientific and standardized, so that the enterprise can achieve the business goal better. It focuses on the management of s
